\VIL'LIAM J. KEEP, OF DETROIT, MICHIGAN, ASSIGNOR TO THE MICHIGAN STOVE COMPANY, OF SAME PLACE.

ESPECIFICATION forming part of Letters Patent No. 888,979, dated September 4, 1888.

(No model.)

To all whom it may concern:

Be it known that 1, WILLIAM J. KEEP, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Stoves, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a side view of part of a stove with my improved fire-pot attached. Fig. 2 is a vertical section through the line as x in Fig. 1. Fig. 3 is a horizontal section through the line 3/ in Fig. 2; and Fig. 4 is a perspec- 5 tive view of part of a ring and the operatingpinion detached. Fig. 5 is a perspective detail showing portions of the supporting-ring and of the frame.

This invention relates more particularly to heating-stoves, but parts thereof may be applied to other stoves; and the invention consists in the peculiar construction and arrangement and the combination of parts, hereinafter more particularly described, and then deli- 2 nitely pointed out in the claims.

Referring now to the details of the drawings, which show what I consider the preferable form of my improvement, A represents the main frame of the stove, having on its inner side logs or supports a a a, on which rests the ring B, having a. suitable number of friction-rollers, C, mounted therein to properly so pport the lower pot-ring, D. On the underside of the ring B is a lug, b, that slips over the U edge of the lug a, and thus keeps the ring 13 from accidentally shifting. A lug, j, on the doorJ keeps the ring from rising accidentally.

On one side of the ring B rises a standard, I), in which is fitted a tapering sleeve, E, which forms a bearing for the tapering shaft f of the pinion F, which is held in place by the saddle G, which forms the inner bearing for the shaft f, and is secured by bolts and nuts to the stand ard b. The lower part of this saddle G terminotes in toes, which slip into holes in the ring 13, and its upper part is provided with lugs,

which pass behind depending lugs h on a ring,

H, that forms part of the frame-work of the stove. The sleeve E is provided with a collar, e, (see Fig. 4,) which is held between the saddle G and standard I) in such a manner as to hold the same in position.

The lower fire-potring, D, is provided with teeth d, into which meshes the pinion I and it also has a rim, d, which rises (preferably) even with the top of the teeth and serves the double purpose of strengthening the teeth and preventing ashes, cinders, &c., from getting between the teeth.

Resting on the ring H is the upper pot-ring, I, the lower edge of which is beveled and drops inside of the ring D, which is provided with an offset, so that its lower inner side is substantially in line with the inner side of the upper pot-ring, I. 6;,

The lower front doors are arranged so that the mica-filled portion is inclined, which prevents the dust, 800., that sifts downward from the fire-pot from settling thereon. The pokeholes, instead of being formed in the frame, as usual, are formed in the bottom of the lower doors, which are provided with extensions for that purpose. This allows of a larger opening to draw out the fire-pot, 850., when re quired, or for other purposes. The uppersec- 5 tion of the fire-pot rests on its supportingplate in such a manner that while it bears evenly all around and is held securelyin place it can move laterally in its bearings sufficient to allow for expansion, and can readily be turned in its bearings, if desired. It is located in such a position above the lower fire pot ring that when the former expands downward, grows larger, or becomes distorted from heat or use it will not come in contact with the revolving part. By the peculiar arrangement of the two fire-pot rings and the use of the rim (1' very little, if any, of the ashes will escape between the two rings.

Vvheu it is desired to remove the lower sec- 0 tion of the fire-pot, the front doors are opened, and by lifting the lug b so that it will slip over the lug a and pulling around that part of the ring so as to partially revolve said ring the other side moves backward, so as to carry the 9 5 standard b away from the frame,which would otherwise preventits coming out. The stand ard and its attachinents-the saddle, pinion, Ste-are thus carried backward, so that the saddle, 850., escape the lugs hand the frame of rco the stove, and then the ring B and the lower fire pot ring can both be drawn out through the lower door-opening when the doors are swung back.

The upper left-hand corner of the right side door is provided with an opening to receive the sleeve, and is fitted to the same, whereby the door helps to support the bearing to make a tight joint.

It will be seen that one of the friction-rollers is directly under the cog-wheel, which will prevent any accidental tipping and displacement of the ring.

From the above and the drawings it will be seen that the fire-pot is made in two sections,

both of which can be setin or removed through the openings, and that the lower section and its supporting-ring and operating device can be assembled outside of the stove and then set in place all together through the dooropenings. Should occasion require their re moval, they can be readily removed and replaced.

In some cases instead of using the lugj to hold down the ring B, I useabutton, asshown by dotted lines in Fig. 2. Instead of the rollers shown, balls may be used; but I prefer rollers. Both of these devices I should consider the equivalents of those for which they are substituted.

What I claim as new is 1. In a stove, a sectional fire-pot having an upper section with closed sides and a flange at its upper edge, and a lower section provided with teeth near its upper edge and a pinion gearing with teeth of the lower section and protected from contact with the ashes and cinders of the upper section, said upper section extending below the highest portion ot the lower section and resting on a support independent thereof, as set forth.

2. In a stove, the combination, with its casing, a toothed fire-pot, D, and pinion F, of the ring B,iuclosed by the casing and supporting the fire-pot section, and having a standard forming a bearing for said pinion F, sub stantially as described.

3. In a stove, the combination, with a toothed fire-pot, D, a pinion, F, and saddle G, of the ring B, forming a support for said pot, and having a standard, b, constructed to serve as a support for the saddle, and to form with the same a bearing for the shaft of the pinion, substantially as described.

4. In astove, the combinatiomwith a toothed ing the double purpose of strengthening the teeth and keeping the ashes therefrom, substantially as described.

6. In a stove, and in combination with a lower toothed revolving section of a fire-pot having a rim inside the circle of teeth to pre- 4 vent the ashes entering between them, a second section having its bottom edge of smaller diameter than the lower section and set within the upper edge of the lower section, substantiall y as described.

7. In a stove, and in combination with a fire pot made up of two ring-sections, one set above the other, a frame provided with a separate bearing for each section of the firepot, and upper and lower door-openings, each of sufficient size to admit one section of the fire-pot, substantially as described.

8. In a stove, and in combination with a frame having supports for the fire-pot and a removable fire-pot ring having lugs resting on said supports, a door having a lug arranged to pass over said fire-pot ring, whereby the ring is held in place when the door is closed, but readily removed when the door is open, substantially as described.

9. In a stove, and in combination with a toothed fire-pot, a pinion meshing therewith, a standard for the support of the shaft of said pinion on one side thereof, and asaddle, G, attached to said standard, for holding said pinion in place, substantially as described.

10. In a stove, and in combination with the frame thereof, a movable fire-pot and pinion for operating the same, a suitable support, as the standard b, detachably connected with the casing of the stove, and, as a means for supporting said operating-pinion, a sleeve, 1*],

fastened to said support, substantially as described.

In testimony whereofIaffix my signature, in presence oftwo witnesses, this 29th day ofJuly, 1886.
